BMW is going to replace engine ---misfiring issue

[kashmir]

this is the follow up thread for the engine misfiring issue that i had created about a month ago. As i mentioned in that thread, BMW had replaced intermediate levers twice so far without any resolution of the problem. They have , now, agreed to replace the engine. Initially, my dealer was suggesting that it was not a good idea to put a new engine in a 2005 x5. They told me that BMW would offer me $3000 towards a new purchase. I insisted that the engine be replaced as the cost of engine replacement would be lot more or the actual cost of repair should be put in towards new purchase. I was told that it would cost BMW $13k to replace then engine. Today, service manager told me that BMW would not contribute towards new purchase. engine replacement would be my only option. I am sensing foul play by the dealer here. Is there anyway I can contact BMW directly regarding this issue. I really dont think it is a good idea to put a new engine in an almost 8 year old truck.

really need help here.

thanks very much
